Display issue with IN-17 6-digit board

I see it's been a LONG time since anyone has posted... hopefully this forum is still monitored.
I've got a pair of V3 Arduinix boards and a pair of UNO's. I have one 6-digit IN17 board.
I build these a few years ago, both tested and working, as was the IN17 board.
I just dragged everything out of mothballs, misplaced my UNO's, so ordered two more.
Flashed them with the code in the download section and connected everything.
Both Arduinix V3 boards and both Unos have the same display on the IN17 board.
The first digit has both the 1 & 2 turned on. The second digit is blank.
3rd digit has a 2 displayed (Not sure what the actual time is on the Arduino).
4th digit has at least 3 elements lit... this digit will change, sometimes displaying a '3' Clear as day, but looks like normally has 3, 4 and 5 lit.
5th digit is off. Haven't seen anything come on in this tube,
and 6th digit always has the '3' on. As this should be seconds, I would expect this to increment, or at least flick.
So my thoughts are that the issue is with the IN-17 PCB... since both V3 and Unos give me the same results.
I did try a second set of cables as well just to be sure... same result.
Any thoughts on this?? Am thinking about just picking up another IN-17 board and trying it.
It's curious that everything worked before going into storage, but doesn't now.
I've been unable to locate my original Arduinos, the two I am using now just showed up yesterday. I will concede there is a chance
that they both have some kind of identical issue that would cause this as well. Just looking for ideas on what I can check.

Thanks!
